I prefer to give the course to couples because when your partner knows what goes on in your body, knows what relaxes you, knows which breathing is better in which stage, than your partner can support you way better than just holding your hand!
And if you know that your partner knows all this, you can relax much better! The birth of your baby will be much more of a team effort!
But if your partner really has no opportunity to join you, you can also bring someone else like a friend, sister or your mother. Someone you feel comfortable with. You can also come alone, but we are doing some exercises which you need a partner to do it.
